Problems opening FM13 Go on iPad

[JackieN]

Recently I've been having problems opening File Maker (13) Go on my iPad.

 

When I close Go on the iPad then reopen the program the database is whited out/all white and I have to close the Go and reopen it again.

 

Any reason what could cause this and how to fix it? Is it anything to do with the fact that the Database is edited in FMA12, but being used on Go 13?
